The multi-level sorter assembly of claim 3 wherein the continuous elevator includes a first flexible member in the form of a loop drivingly connected by a plurality of drive wheels and a second flexible member in the form of a loop drivingly connected by a plurality of drive wheels, the first flexible member and the second flexible member being members of the same shape and size and having two vertical sections, the first flexible member being spaced parallel to and not side by side with the second flexible member, the elevator car being movably connected to both the first flexible member and the second flexible member.

5. The multi-level sorter assembly of claim 4 wherein the first flexible member partially coincides with a rectangular projected surface formed by the second flexible member.

6. The multi-level sorter assembly of claim 4 wherein the continuous elevator includes two side-by-side first flexible members and two side-by-side second flexible members, and wherein the nearest single first flexible member and second flexible member form a set of drive mechanisms, and the two sets of drive mechanisms are in mirror-image relationship, and the elevator car is movably connected to both first flexible members and both second flexible members.

7. The multi-level sorter assembly of claim 4, 5 or 6 wherein the first and second flexible members are chains and all of the drive wheels corresponding to the first and second flexible members are sprockets.

8. The multi-level sorter assembly of claim 1 wherein the infeed conveyor includes independently operable and contiguous conveyor sections and buffer sections, the buffer sections interfacing with the elevator car cargo.

9. The multi-level sorter assembly of claim 1 wherein each level of said sortation conveyor is provided with a shuttle that is reciprocally movable along the length thereof, said shuttle abutting said exit conveyor and said cellular cargo.

10. The multi-level sorter assembly of claim 1 wherein the plurality of bays on the same side of the sortation conveyor in an up-down relationship with each other correspond to different destinations, or wherein the plurality of bays correspond to the same destination.
